[Abstract]:
The scale of Laboratory Electrolyzer is a common phenomenon in our daily life. The kettles, pipes, etc., industrial equipment, industrial boilers, etc. in the home life will form a layer of scale on the metal surface after a period of use.

The scale of Laboratory Electrolyzer is a common phenomenon in our daily life. The kettles, pipes, etc., industrial equipment, industrial boilers, etc. in the home life will form a layer of scale on the metal surface after a period of use. White, gray, light yellow, yellow Gray, etc. Some areas have more scale deposits, and some areas have less scale. Then, what is the source of these deposits and what are the differences between regions?

Laboratory Electrolyzer

Due to the presence of a certain amount of calcium and magnesium salts in the water, such as bicarbonate, carbonate, sulfate, chloride, silicate, phosphate, etc., it also contains sediment and organic matter. These salts undergo physical and chemical changes during heating to form scale.

Among them, the calcium bicarbonate contained in the water will decompose into insoluble calcium carbonate in the process of increasing the water temperature. Usually, the main components of the scale are calcium carbonate and calcium phosphate. There is also a certain amount of calcium sulfate dissolved in the water; calcium silicate and other inorganic salts, as the water evaporates, their concentration in the water increases, and when the concentration exceeds the solubility, precipitation will be formed and deposited on the heat transfer surface . Rust scales such as rust and patina on metal surfaces in industrial boilers are also converted into scale components. Because most of the scale is composed of inorganic salts, it is called inorganic scale, and these scales are dense and hard, so they are also called hard scale. The composition of the actual scale is quite complex and the composition varies with the water quality, so the scale in different regions should be analyzed in detail.

According to the main components of the scale of Laboratory Electrolyzer, it is usually divided into carbonate scale; sulfate scale, phosphate scale, silicate scale and rust scale.
